Definitions
- This invention pertains to a hair dryer employing a radiator made of a ceramic adapted when heated to radiate far-infrared radiation.
- a hair dryer employs a heating wire, such as a nickel- chromium (Ni-Cr) wire, and relies upon heat convection only to dry a user's hair.
- a heating wire such as a nickel- chromium (Ni-Cr) wire
- a hair dryer As exemplified in United States Patent No. 6,205,677 (from International Application No. PCT/KR99/00336) it has been known for a hair dryer to employ a heater radiating far-infrared radiation.
- the heater radiating far-infrared radiation is a halogen heater, which comprises a heating wire within a gas-filled, quartz tube.
- Such a hair dryer employs far-infrared radiation as well as heat convection to dry a user's hair.
- This invention provides a hair dryer employing a radiator made of a ceramic, such as a bio-ceramic, which is adapted when heated to radiate far- infrared radiation.
- a ceramic suitable for the radiator is available commercially from Tae Yang Ind. Co. of Majungong 87-1, Sugu, Inchon, Korea, under its CELAMLNE trademark.
- the hair dryer comprises an elongate body, which has an inlet end defining an inlet and an outlet end defining an outlet.
- the hair dryer further comprises a fan, which is adapted when driven to draw air into the inlet, to move air through the elongate body, and to blow air from the outlet, and an electrical motor, which is adapted when energized to drive the fan.
- the hair dryer further comprises an electrical heater, which is mounted within the elongate body, between the fan and the outlet.
- the ceramic radiator is mounted to the elongate body, at or near the outlet end, so as to be radiantly heated by the electrical heater when energized and so as to be additionally heated by air being moved through the elongate body by the fan when the electrical motor is energized and being heated by the electrical heater when the electrical heater is energized.
- the elongate body, at or near the outlet end, and the ceramic radiator have respective formations, which enable the ceramic radiator to be snap- fitted onto the elongate body, at or near the outlet end.
- such formations enable the ceramic radiator to be snap fitted onto the elongate body, at or near the outlet end, within the outlet.
- the electric heater is configured as a grille having plural apertures, through which air can flow when moved through the elongate body by the fan when energized.
- Figure 1 is a longitudinal, cross-sectional view of a hair dryer employing a ceramic radiator, as discussed above, and constituting a preferred embodiment of this invention.
- Figure 2 is a transverse, cross-sectional view taken along line 2-2 of Figure 1, in a direction indicated by arrows.
- a hair dryer 10 employing a ceramic radiator 100, as discussed above, constitutes a preferred embodiment of this invention.
- the ceramic radiator 100 radiates far-infrared radiation, i.e., electromagnetic radiation having a wave length in a range from approximately five microns to approximately fifteen microns.
- the hair dryer 10 comprises an elongate body 20, which has an inlet end 22 defining an inlet 24 and an outlet end 26 defining an outlet 28 and which has an attached handle 30 mounting an electrical switching means 32.
- the elongate body 20 is lined with thermally insulative materials 34, 36, of types used conventionally in hair dryers.
- the hair dryer 10 further comprises a fan 40, which is adapted when driven to draw air into the inlet 24, to move air through the elongate body 20, and to blow air from the outlet 28, and an electrical motor 50, which is adapted when energized to drive the fan 40 via a rotary shaft 42.
- the hair dryer 10 further comprises an electrical heater 60, which is mounted within the elongate body 20, between the fan 40 and the outlet 28 and which comprises an elongate coil 62 of a heating wire, such as a nickel-chromium (Ni-Cr) wire.
- the elongate coil 62 is mounted within the elongate body 20 via mounting tabs 66.
- the fan 40 and the electrical heater 60 are controlled by the electrical switching means 32, through which the fan 40 and the electrical heater 60 are connectable to a source (not shown) of electrical power.
- the electrical switching means 32 may comprise a single switch 44 to control the fan 40 and to control the electrical heater 60 or, if desired, a separate switch (not shown) to control the fan 40 and a separate switch (not shown) to control the electrical heater 60.
- the fan 40 and the electrical heater 60 may be thus controlled at a single setting for each or at plural, selectable settings for one or for both.
- the ceramic radiator 100 is configured as a grille having an outer, generally cylindrical edge 102 and having plural apertures 104, which are defined by crossed members 106 and through which air can flow when moved through the elongate body 20 by the fan 40 when energized.
- a generally tubular adapter 110 having an inner end 112, an outer end 114, and two circumferential, radially inwardly projecting ribs 116 is provided, in which the ceramic radiator 100 is mounted, between the ribs 116.
- the elongate body 20, at the outlet end 26, and the generally tubular adapter 110, at the inner end 112, have respective formations 108, 118, which enable the generally tubular adapter 110 to be snap-fitted onto the elongate body 20, at the outer end 26, within the outlet 28, whereby to mount the ceramic radiator 100 onto the elongate body 20, at the outlet end 28.
- the ceramic radiator 100 Being mounted to the elongate body 20, at the outlet end 26, as described above, the ceramic radiator 100 is mounted so as to be radiantly heated by the electrical heater 60 when the electrical heater 60 is energized and so as to be additionally heated by air being moved through the elongate body 20 by the fan 40 when the electrical motor 50 is energized and being heated by the electrical heater 60 when the electrical heater 60 is energized.
- this invention enables a ceramic radiator, such as the ceramic radiator 100, to be readily adapted for any hair dryer having an elongate body with suitable formations enabling a flow concentrator or a flow diffuser to be snap fitted onto the elongate body, at or near an outlet end of the elongate body.
- the hair dryer 10 can be effectively operated at lower temperatures and with higher efficiencies.
